1 / 5 page 71 ©2009 Littelfuse, Inc. Specifications are subject to change without notice. Transient Voltage Suppression Diodes Revision: January 09, 2009 Axial Leaded – 500W > SA series SA Series Please refer to http://www.Littelfuse.com/series/SA.html for current information. The SA Series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. Description SA Series TVS devices are ideal for the protection of I/O interfaces, V CC bus and other vulnerable circuits used in telecom, computer, industrial and consumer electronic applications.
